In scanner audio that was apparently broadcast by CBS affiliate KCAL in Los Angeles on Tuesday, officers can be heard yelling to “burn this mother f*cker” prior to a fire that swept through the cabin that was thought to be where fugitive and murder suspect Chris Dorner had holed himself up in.

“Investigators have located charred human remains within the debris of the burned out cabin,” McMahon said.

Dorner, who was a Los Angeles police officer from 2005 to 2008, is suspected in the murders of four people, including a San Bernardino County Sheriff’s deputy, a Riverside police officer and the daughter of a former LAPD captain.
